The part-number for this chip+liquid-cooling bundle is "FD8120FRGUWOX". The liquid cooler is originally made by Asetek, combined with the unlocked base clock multiplier of the FX-8120, it facilitates high overclocking. The cooler is not just a dumb closed-loop, but also packs sensors that connect to the system over USB (internal USB 2.0 header), that let you monitor it via Chill Control software.
